如何在MySQL的PHP​​添加多行

Question

我要加量+ servicecharges + replacecharges + blockcharges + othercharges

，但它不能正常工作，請幫我解決這個問題 感謝

$sql="SELECT CONCAT(monthdate,' ','(',drivernamefuel,')') as drivernamefuel,sum(amount) + 'servicecharges' + 'replacecharges' + 'blockcharges' + 'othercharges' AS amount,drivernamefuel FROM $tablename where carno='$c' AND monthdate BETWEEN '$a' AND '$b' GROUP BY monthdate";

文件＃2：http://www.koolfree.com/ImageUpload/uploads/1381228480.jpg

它正顯示出這些錯誤 警告：被零除在indexssds.php上線51

警告：mysql_fetch_array（）：提供的參數不是在indexssds.php一個有效的MySQL結果資源上線73

這裏是完整代碼請檢查我的更新 感謝...........................

Answer 1

你是不是傳遞參數進行查詢，所以像下面那樣傳遞它

並且您還沒有添加
量+ servicecharges + replacecharges + blockcharges + othercharges內選定的查詢的SUM（..），所以一定要更換

修改您的查詢作爲

$sql="SELECT CONCAT(monthdate,' ','(',drivernamefuel,')') as drivernamefuel, 
    sum(amount + servicecharges + replacecharges + blockingcharges + othercharges) AS amount, 
    drivernamefuel 
    FROM ".$tablename." 
    WHERE carno='".$c."' AND monthdate BETWEEN '".$a."' AND '".$b."' 
    GROUP BY monthdate"; 

Answer 2

我希望這會幫助你。在網頁中刪除qotes（'）和變化SUM（您想總結領域）

$sql="SELECT CONCAT(monthdate,' ','(',drivernamefuel,')') as drivernamefuel,sum(amount + servicecharges + replacecharges + blockcharges + othercharges) AS total_amount,drivernamefuel FROM ".$tablename." where carno='".$c."' AND monthdate BETWEEN '".$a."' AND '".$b."' GROUP BY monthdate"; 

echo $sql; 

回聲查詢並嘗試直接在phpMyAdmin執行查詢。然後檢查你的查詢有什麼問題。問題可能是值要傳遞到查詢

Answer 3

試試這個：

$sql="SELECT CONCAT(monthdate,' ','(',drivernamefuel,')') as drivernamefuel, 
SUM(amount + 
servicecharges + 
replacecharges + 
blockcharges + 
othercharges) AS amount, 
drivernamefuel 
FROM ".$tablename." where carno='".$c."' 
AND monthdate BETWEEN '".$a."' AND '".$b."' 
GROUP BY monthdate";

*注意MySQL擴展is now deprecated and will be removed sometime in the future。那是因爲它是古老的，充滿了壞習慣並且缺乏一些現代特徵。不要用它來編寫新的代碼。改爲使用PDO或mysqli_*。您的查詢往往是SQL Injection。
